New Concept of Doherty Transmitter

NEC has a rich experience in Doherty technology with the first NEC commercial -based t ransmi t ter wi th Doher t y ampl i f iers manufactured in 2011 for Tokyo Metropolitan area, achieving drastic improvement in power consumption (more than 40% better than the existing model). NEC market share of Doherty TX segment in Tokyo has now reached to nearly 50%. And this time, by making the most of this brilliant experience, NEC proposes DTL-30 series with a new concept of Doherty transmitter for global customers.

The core philosophy of NEC Doherty transmitter is to enable the customer to always enjoy the best energy ef ficiency of each selected channel (up to 38%). By initially fixing the operational frequency of each PA unit into a single channel, DTL-30 achieves the most beneficial and appropriate form of Doherty transmitter. Once users become needed to change channel frequency, a bit of time and work will be requested. But the process is simple; only a few components of the amplifiers have to be replaced and it neither requires any special instruments nor skills. The customers may have to be asked to take such a little burden, but there is no more concern that the enjoyable per formance would be fluctuated depending on the designated channel. Minimal lifetime cost solutions (both CAPEX and OPEX efficient) would be effectively ensured.
